ROOFING.

SPECIFICATION forming part of Letters Patent No. 453,470, dated Tune 2,1891.

Application filed January 17, -1 891. Serial No. 378,149. (No model.)

To all whom it may concern:

Be it known that we, JOHN J. GEIGER and LYMAN KNAPP, of Clyde, in thecounty of Sandusky and State of Ohio, have invented certain new anduseful Improvements in Roofing; and we do hereby'declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse it, reference being had to the accompanying drawings, which formpart of this specification.

Our invention relates to an improvement in roofing; and it consists inthe combination of a strip or piece which is formed from a single sheetof metal and is bent or doubled so as to form a double T with the sheetsout of which the roof is formed, and which have their edges bent so asto fit in the sides of the double T and a cap which is placed over theupper flanges of the double T'and the roofingplates, and then bent down,as will be more fully described hereinafter.

The object of ourinvention is to provide a metallic roofing in which theparts are quickly and readily applied together, and then secured inposition, without requiring the skilled labor which has usually to beemployed in this connection.

Figure 1 is a detail View showing allot the parts of a portion of a roofready to be put together. Fig. 2 is a similar view showing the sameparts put together, but the cap-piece not bent over. Fig. 3'is avertical section of the parts when completed. Fig. 4. is a detail viewof an end piece.

A represents a sheet of metal which has been bent so as to form a doubleT, and which is to be nailed directly upon the roof at its lower edges.The sheets or plates B which form the roofing proper have their edgesbent into a U shape, so as to fit within the flanges of the part A, andtheir the cap-piece O is applied over the upper edges of the double T Bwill be secured together. The edges of the cap are then closed together,and the flanges inclosed in the cap are bent down, as shown, so as toform a tight joint.v

At the ends of the roof, instead of having the double-T pieces A, theflanged end pieces G are used, and which pieces have a flange H upontheir inner sides about one-half way down and two flanges a at theirupper edges. Only one flange is formed at the center, because the sheetsor plates B are applied only to the inner sides of the end pieces. A capis then applied to the top flanges, which are then turned down, as shownin Fig. 3.

As a sheet-metal roof constructed as here shown and described can bereadily applied without the help of skilled labor, a great reduction inthe cost of the roof is elfected and an absolutely tight joint withoutsolder is made.

Having thus described our invention, we claim- In a metallic roofing,the combination of the double -T pieces, the roofing-plates having theirouter edges made U-shaped, so as to fit in the sides of the double Ts,and the caps which secure the double Ts and the roofingplates together,substantially as shown.

In testimony whereof We affix our signatures in presence of twowitnesses.
